Title: High voltage generator
Inventor: NAKATANI MASAHIDE
IPC: G03G15/02
Filed: 1986-04-14
Abstract: PURPOSE:To execute a destaticization and an electrification of positive and negative polarities, by providing two pieces of corona discharge, wires, and applying alternately a voltage of the positive polarity and a voltage of the negative polarity to one of them and the other, respectively, and executing an AC corona discharge. CONSTITUTION:At the time a power source is inputted, a controlling circuit 12 is started, switch elements Q1, Q2 conduct alternately, an AC voltage is induced in a boosting transformer 10 and 11, and in a corona discharge wire 8 which has been connected to a diode D1, a corona discharge of the positive polarity occurs, and also, in corona discharge wire 7, a corona discharge of the negative polarity occurs, a corona discharge current which has become an AC substantially flows, and a photosensitive body 9 is destaticized and electrified. The surface potential of the photosensitive body 9 is proportional to a DC portion contained in the corona discharge current I, but the corona discharge current I is varied by humidity and temperature, the atmospheric pressure and contamination of an electrode, etc., therefore, the DC portion is detected by an output detecting circuit 13, and a feedback control is executed so that it becomes a prescribed value. In this way, not only the destaticization but also the electrification of the positive and negative polarities can be executed.

Title: Insulating gate field effect transistor
Inventor: TERADA KAZUO
IPC: H01L29/10
Filed: 1979-07-03
Abstract: PURPOSE:To obtain a double channel dope and short channel MOSFET for high speed and high density IC by using a semiconductor substrate with the impurity concentration of predetermined range wherein the amount of dope of deep channel and the length of channel are established as predetermined. CONSTITUTION:Punch-through will effectively be checked if a shallow channel part is made high concentration for an MOSFET having P-type channel dope layers 26, 27 of two layers, which are deep and shallow respectively. On the other hand, a threshold voltage is determined by the concentration of a P-type substrate 21 and the dope amount of all channels. If the concentration of the substrate is set at about 3X10<14>cm<-3>-1X10<15>cm<-3>, the substrate voltage dependence on the threshold voltage becomes small. If a deep channel dope layer 26 with predetermined concentration is provided around a depth of 0.4mum from the surfaces of a gate insulating film 24 and the substrate, punch-through at the substrate under the layer 26 will be prevented. The dose amount of the shallow layer 27 is automatically determined from the dose amount of the layer 26 as the total amount of the channel dope is decided by determining the threshold voltage and the concentration of the substrate. Thus, a high speed MOSFET will be obtained by this structure.

Abstract: PURPOSE:To form an impurity layer up to the deep part of a trench side surface, and increase the capacitance of a capacitor, by using an ion implantation mask having an aperture whose end-portion is formed in a tapered-type. CONSTITUTION:A resist mask 12 provided with an aperture having a taper angle theta1 is formed. After a trench 13 is formed by etching a P-type silicon substrate 11, arsenide ion 14 is implanted at an angle theta smaller than the angle theta1 with respect to the silicon substrate 11, and an impurity layer 15 is formed on the side wall of the trench. The resist mask 12 is eliminated, thermal oxidation is performed in an oxygen atmosphere, and a capacitor oxide film 16 is grown on the P-type silicon substrate and the surface of the trench 13. Successively polysilicon containing impurity is deposited on the capacitor oxide film 16, and turned into a capacitor electrode 17. Thereby the impurity layer 15 can be formed on the whole side surface of the trench, so that the capacitance of a capacitor can be increased.

The α-glucosidase is capable of removing the unreacted maltose, maltooligosaccharide, isomaltose and isomaltooligosaccharide from a reactional product by using the enzyme protein in a production process for the trehalose and providing the high-purity trehalose. The protein is prepared by carrying out the site-specific mutation treatment in a part of the gene of the α- glucosidase protein according to a conventional method and then expressing the gene in a host cell.

Filed: 1983-05-13
Abstract: PURPOSE:To increase considerably the output for reproduction by providing a magnetic signal detecting section and an electronic cooling means to inhibit a rise in the temp. of a thin film of a magneto-resistance effect type element by electric power consumed and to increase the fusing current density. CONSTITUTION:Electronic refrigerating elements 8 are adhered to a cooling surface 9 with hot grease in-between. In the figure, 11 is an electric conductor. Each of the elements 8 is composed of two kinds of elements, that is, a p type semiconductor and an n type semiconductor such as bismuth and telluride. When electric current is allowed to flow from the n type semiconductor to the p type semiconductor, the cooling surface 9 is cooled, and a heating surface 10 is heated. The surface 9 cools an Al substate 1, and the substrate 1 cools a thin film 3 of an MR element. The generation of heat by electric current flowing through the MR element is inhibited, and Jmax is increased. Signal magnetic flux generated by the magnetization of a signal on a recording medium in a magnetic signal detecting section is led to the thin film 3 throug a thin Fe-Ni film 2 to change the magneto-resistance of the film 3, and the magnetic flux is returned to the surface of the recording medium through a thick Fe-Ni film 5. Such action is suitable for the reproduction of a vertically magnetized signal.

Title: Visualizing method for latent image
Inventor: KINOSHITA KOUICHI
IPC: G03G15/06
Filed: 1981-06-01
Abstract: PURPOSE:To prevent a non-image part from dirt and find resolution with high image strength by applying DC and AC voltage to a toner holding surface arranged in the reverse side against a glid arranged close to a latent image holding surface. CONSTITUTION:A latent image holding surface 4 is like a drum and a toner holding member 1 consists of a roller.

An AC power source 3 and a DC power source 5 apply voltage to the toner holding member 1 and a DC power source 6 and an AC power source 7 apply voltage to the glid 2. The AC power source 7 helps the toner to sputter from the surface of the glid 2 to  the latent image holding surface 4 and the DC power source 6 prevents the toner from being adhered to a non-image part. The DC power source 5 is the one for determining the fundamental relation of electric potential between the toner holding member 1 and glid 2. Thus, the non-image part is prevented from dirt and resolution with high image strength can be found.

Abstract: PURPOSE:To reduce the vibration of an actuator and, at the same time, to prevent positioning accuracy from being lowered by the wear of a bearing, by assuming a reference plane which passes through the center of gravity of a carriage assembling body and intersects the forward and backward moving directions of the carriage at right angles and arranging plural bearings symmetrically about the reference plane. CONSTITUTION:The fitting angle of each bearing is 45 deg. against both Z-axis and Y-axis and, therefore, the bearing 5a of cross section (a), bearing 5b of cross section (c), and bearings 5c and 5d at the central part are symmetrical about a reference plane (cross section b) which passes through the center of gravity G when it is viewed from both Y- and Z-directions and is normal to the main axis (X-axis) of a carriage 1 together with the arrangement of the bearings and a pressing spring kc. Since the pressing spring kc is provided only one at the cross section (b) of the center, the static reaction forces applied to the bearings 5a and 5b are equal to each other and fluctuation of the dynamic pressing forces caused by vibrations also become equal to each other. Therefore, vibrations of the carriage 1 can be reduced and, at the same time, the lowering in the positioning accuracy caused by the wear of the bearings can be prevented.
